Black Shoes:
Price = $79.45
Markup = 44% of 79.45 = 0.44 x 79.45 = $34.96
Price after Markup= $79.45 + $34.96 = $114.41

Brown Shoes:
Price = $133.99
Mark down = 21% of 133.99 = $28.14
Price after Mark down = $133.99 - $28.14 = $105.85

Difference in cost = $114.41 - $105.85 = $8.56

Answer:  The black pair costs $8.56 more than the brown pair. (Answer B)

You want to surround the perimeter of a garden with 35 stones. You need to place a certain number of large and small stones, and
murzikaleks [220]

Answer: A) x + 4x = 35;  7 large stones and 28 small stones

======================================================

Explanation:

x = number of large stones

4x = number of small stones

x+4x = total number of stones = 35

x+4x = 35 is the equation to solve

-----------

Let's isolate x

x+4x = 35

5x = 35

x = 35/5

x = 7 large stones are needed

4x = 4*7 = 28 small stones are needed

If a and b represent numbers, which of the following statements represents the commutative property of multiplication?
Gemiola [76]

The commutative property of multiplication states that the numbers can be multiplied in any order.

a+b = b+a : Commutative property of addition

a*b = b*a : Commutative property of multiplication

a+0=a : Additive identity property  

a*1 =a : Multiplicative identity property  

Answer : a*b =b*a

Match the real-world problem to its constant of proportionality.
irakobra [83]

Answer:

a. $18.36 for 3 pizzas  :  k  = 6.12

b. $4.17 for 3 pounds of bananas .   k  = 1.39

c. $16.48 for 4 pounds of potatoes .  k  = 4.12

d. 2 cups of flour to make 24 cookie .  k  = 12

Step-by-step explanation:

PROPORTIONALITY:

Two quantities x and y are said to proportional to each other

if for x ∝ y , x = y k.

Here, k is called the PROPORTIONALITY CONSTANT.

⇒x \propto y \implies k = \frac{x}{y}  

Now, for the given quantities:

a.  $18.36 for 3 pizzas [box]    

Here, k = \frac{x}{y} = \frac{18.36}{3}  = 6.12

So, the proportionality constant is 6.12.

b. $4.17 for 3 pounds of bananas [box]

Here, k = \frac{x}{y} = \frac{4.17}{3}  = 1.39

So, the proportionality constant is 1.39.

c. $16.48 for 4 pounds of potatoes [box]

Here, k = \frac{x}{y} = \frac{16.48}{4}  = 4.12

So, the proportionality constant is 4.12.

d. 2 cups of flour to make 24 cookies

Here,  k = \frac{x}{y} = \frac{24}{2}  = 12

So, the proportionality constant is 12.

A polynomial is to be constructed that will touch the x axis at most 8 times. What is the minimum degree of the polynomial?
slamgirl [31]
Every degree is a touching point since each root factor is an  x intercept

therefor the answer is 8th degree
